The generic name of the type species, Elopteryx nopcsai is derived from two Ancient Greek words meaning 'marsh wings', and the specific name was kept in honor of Nopcsa.
There are a lot of similarities found between the Bradycneme and Elopteryx and a lot of specimen material that was referred to as Elopteryx was later reassigned to Bradycneme.
Another specimen or bird remains whose exact location and time of discovery are unknown had fossils dated to the Late Maastrichtian age and were initially referred to as Elopteryx but later reassigned and considered to be of a pelecaniform seabird by Charles William Andrews as history states.
